Patented Nov. 5, 1907.. i

' To all whom it may-concern:

Be it known that we, JOHN WALTER LEONARD and HARRY EDGAR BROWN, both citizens of the United States, and residents of Washington, in the county of Washington and Stateroi Pennsylvania, have invented a new and Improved Gearlngfol' which the following is a full, clear, and erect description.

a This invention is designed to provide a gearing, strong .in construction, effective in operation and durable in use, especially adapted to be employed in connection with convertible gas and steam engines for operating oil wells.

The special objects of the invention will be fully understood from the following description and accompanving drawings, in which drawings like characters of reference indicate, like parts throughout the views,

and' in which Figure l is a vertical transverse section, partly in side elevation, of a device embodying our invention; and Eig. 2 is a transverse section taken on the line 2-2 of Fig. 1.

As illustrated in the drawings, 1 represents the drive shaft of an engine keyed or otherwise secured to a stub section 2 having a reduced outer end 2 which is journaled in the off-set portion 3 and hub 4 of a head 5. Thishead is adapted to be firmly secured to abase or sillby means of bolts 6, and is preferably provided with a laterally extending annular rim 7 and a vertical strengthening rib 8. A sleeve 9 is mounted upon the hub 4 of said head and provided with acani slot 10 which engages a stud 11 attached to the hub 4, and preferably provided with an anti-friction` roller 12 adapted to bear against the edges of the sleeve 9 form: ing the slot 10. The sleeve 9 is also provided with an outer head 13 having an aperture adapted to receive Va vpin 14 provided with a threaded outer end engaging lock nuts 15. A collar 16 is'iixedly secured to the piu' 14 and bears against the inner wall of the head 13 of said sleeve. An operating lever 17 is attached to said sleeve, by means of which the head 9 may be partially rotated on the hub 4 and moved bodily .longitudinally of said hub. The pin 14 engages a held within the aperturesZl 0f the head 22.

An annular head 24 is rotatably mounted upon the reduced end 2 of the driving f shaft, and provided 'with a laterally. extending stud`25 to which is p'ivotally i v f attached the inner end of a connecting rod 26, the Outer end of which rod is pivotally attached to the free end 27 of a band 28, the opposite end of said band being xedly secured to an arm 29. The connecting rod -26 is preferably provided with a turnbuckle 30 by means of which the free end of the band 2.8 may be adjusted relatively to the stud 25 of the head 24. The arm 29 extends laterally from a hub 31 having a threaded connection with a sleeve 32 freely journaled upon the stub shaft 2. Stems 33 extend outward from the inner vend of the sleeve 32 and support beveled .gears 3 4 mounted to rotate on the outer ends of said stems. The teeth of said gears meshwith a laterally toothed gear 35 which is ixedly secured to the driving shaft by means of a key 36, or otherwise, and said gears also mesh with a laterally toothed ring or gear 37 formed on an annular web 38 of a driving wheel having an inner sleeve 39 mounted to rotate freely on the sleeve 32, 'and an outer rim 40 adapted to operate adriving belt 41. The driving wheel is also preferably provided with an inner head 42, detachably secured by means of studs 43 to the driving wheel, and provided Vwith a central hub 44 adapted to rotate freely'on the driving shaft` A collar 45 is mounted to turn freely upon theflangey 39 of the driving wheel, and is provided with a stud 46 to which is pivotally attached the inner end of a connecting rod 47 provided with a turn-buckle 48, the outer end of said rod being connected with the free end 49 of an inner band 50 adapted tobear against the inner periphery of the driving wheel. Springs 51 are connected with'the free ends of the gripping bands 28 and of said bands from contact'with the driving wheel and l against a wearingdoloclr57l which bears against thev sleeve 39 of the driving wheel.

When the device is in use and the operating lever 17 is in the position indicated in Fig. 1, the stud 11 is at the lower and outer portion of the slot 10 formed in the tent within the longitudinal aperturei18 of the end of the sleeve, bringing the collar 16 of said pin in Contact sleeve 9, and the pin 14 is projected to its greatest exhollow end of the shaft 2, the head 22 iscan'ied inward v 54, or'the adjusting screw 56 connected. therewith, .bears against the wearing block 57 and bindsthe ring Y* w ward on the reduced end 2rl of the driving shaft, bring-- cylinder in its place, or the reverse.

45 upon which said'lever is mounted, to the sleeve 39 of the driving pulley, and the connecting rod 47 pivotally attached vto said ring forces the free end of the gripping band .50'against the inner periphery of the outer portion of the driving wheel thereby locking together said, drivingwheel, the gripping band 50, arm 29 and Asleeve 32, upon which said arm is mounted. When the sleeve 32 is locked to the driving wheel the beveled gears 34 are inoperative, for the reason that the' sleeve 32 moves with the gear 36, and all of the said parts rotate with the drive shaft l. At such time the outer gripping band 28 is free from contact with the rim 7 of the head `5, and rota-tes with the arm 29 and the head `24, which also rotate with the arm 29, sleeve 32 and the driving pulley, in a forward direction. To reverse the movement of the' driving wheel, so as to rotate backward While the shaft is rotating forward, the operating lever 17 is depressed so that the stud ll. operating in the cam slot l() will cause the sleeve 9 to move bodily outward on the hub 4 of Ithe stationary head 5. Such movement of the sleeve 9 carries the pin 14 outward, thereby causing the head 22 to move outing the outer face of said head against the inner face of' the head 24, and binding said head against the inner wall of the offset portion of the stationary head 5. The inner head 'forms an auxiliary clutch with the main sta-v tionary head, and holds .the head 24 against rotation on the driving shaft l. The outer movement of the head 22 releases the outward pressure on the free end of the lever 54 and consequently releases the pressure exerted by the other end of said lever on the ring 45, and frees the inner gripping band 50 from Contact with the inner periphery of the driving wheel, thereby leaving said driving wheel free to rotate independently of said ring, and arm 29. When the head 24 is clutched to the stationary head 5, the connecting rod 26 attached i tothe stud 25 of said head forces the outer gripping band l.28 against the ring 7 of the main head, and holds the stems 33 and the sleeve 32 with which said stems are connected, against rotary movement on "the driving shaft. As the sleeve 32 and stems 33 connected there with are held against rotary movement, the drive shaft in rotating and the laterally toothed gear iixedly attached thereto, rotate the beveled gears 34 inone direction, which in turn rotate the driving wheel in an opposite directionvloy means of the laterally toothed gear 37 formed on the web 38 of said wheel, thereby causing the driving wheel to rdtate in an opposite direction to that in which the drivjig gear 36 and driving shaft are rotated. To rotate the driving wheel in the same direction as the shaft, the operating lever i7 is raised so as to bring the parts in the position indicated in Fig. l in the manner hereinbefore described.

Enginesused in connection with oil wells are comrnonlyv constructed so as to be driven either by gas or steamby removing the steam cylinderand using a gas of gas engines is generally made short, and not of sufficient length to be used with a clutch pulley. To avoid removing the shaft and inserting a longer shaitlwhen the engine is changed from a gas to a steam engine, we provide the clutch pulley with a stub shaft 2 of its own, having a recessedend, or otherwise adapted to be secured to the main section of the drive shaft. One of The driving shaft the special features of the construction herein shown consists in placing the auxiliary clutches uponl the hub of the wlieel instead of on the shaft, by means of which.

-the thrust of the auxiliary 'clutch is taken ofi the sluit and placed upon the wheel itself. By means of such construction, moreover, driving pulleys of any dimen sions maybe readily and quickly reversed'by the op-".

erator and caused to rotate in the samedirection as the shaft or in a direction opposite thereto, while the ar,

rangement of the gripping bands near the outsideioff the pulley and away fromthe engine enables the friction grips to be readily adjusted. `Engines are com- A monly employed in connection Awith oil wells. in which both steam and gas cylinders are userL 1 1 In the construction shown and described herein, We

We do not desire to bey limited to such construction, however, as other means having similary capabilities may be used without departing from our invention.

Having thus described our invention, what We claim as new and ldesire to secure by Letters Patentfis: v
